Identify the compound that does NOT have dipole-dipole forces as its strongest force. A) CH₂I₂ B) CH₃OCH₃ C) CH₃Cl D) HCBr₃ E) CO₂

Question

Quizplus · Accepted Answer

The molecule with the weakest dipole-dipole forces will be the molecule with the least polar bonds (i.e. smallest difference in electronegativity between two bonded atoms) or a molecule without any polar bonds. In this case, the molecule CO₂ has a triple bond between carbon and oxygen, creating a symmetrical distribution of charge that results in no overall dipole moment. Therefore, it does not have any dipole-dipole forces as its strongest force.
